Perhaps challenge is not axiomatic to life, but merely a perspective. Either we can do something or we can’t — what’s the test? If we require practice or determination to overcome a perceived challenge, either we practice or we don’t, either we’re determined or we aren’t. And if outcomes are beyond our control, a more permanent obstruction could intervene at anytime. Perhaps challenge is merely another part of the everything life provides — in other words, if we look for challenge, we’ll find it.
